Querying & Models

Umbraco 7.6.0+ Umbraco stores identifiers in UDI format for most Umbraco object types. This identifier stores all of the metadata required to retrieve an Umbraco object and is parse-able within text. Example: umb://document/4fed18d8c5e34d5e88cfff3a5b457bf2. UDI's can be used in many of the querying APIs.

DynamicPublishedContent is the dynamic version of IPublishedContent. It has most of the same features as IPublishedContent but allows
for slightly more elegant syntax to render user defined properties with the tradeoff that it is not strongly typed and does not support intellisense.

UmbracoHelper is the unified way to work with published content/media on your website.
Whether you are using MVC or WebForms you will be able to use UmbracoHelper to query/traverse Umbraco published data.

Our.umbraco.com is the community mothership for Umbraco, the open source asp.net cms. With a friendly forum for all your questions, a comprehensive documentation and a ton of packages from the community.
